Clock control indirectly requires access to MFC device, so call it only
if we are sure that the device exists in s5p_mfc_release function.
s5p_mfc_remove() calls s5p_mfc_final_pm(), which releases all PM related
resources, including clocks, so any call to clocks related functions
is not valid after s5p_mfc_final_pm().

Newer MFC hardware have internal clock gating feature, so additional
software-triggered clock gating sometimes causes misbehavior of the MFC
firmware and results in freeze or crash. This patch changes the driver
to use software-triggered clock gating only when working with v5 MFC

Media drivers that use the videobuf2 framework have to give back to vb2

But the exynos-gsc driver isn't doing a proper cleanup so vb2 complains

The struct v4l2_device instance for the G-Scaler is not dyanmically
allocated but a member of the struct gsc_dev. In fact, the assigned
.release callback is video_device_release_empty().
But gsc_register_m2m_device() attempts to release the v4l2_device by
calling video_device_release() in its error path. This is wrong since
the v4l2_device wasn't allocated directly and will be freed once its
parent struct gsc_dev is freed.
While being there, rename the remaining goto label in the error path
to something that better explains the error path cleanup.

The driver don't take into account the differences between packed, semi
planar and multi planar formats when calculating the pixel format bytes
per lines and image size values. This makes GStreamer to fail when the
following formats are used NV12, NV21, NV16, NV61, YV12, I420 and Y42B:
"gst_video_frame_map_id: failed to map video frame plane 1"
Nicolas suggested to use the logic found in the Exynos FIMC v4l2 driver
since does this correctly. So this patch changes the bytes per line and
image size calculation according to what's done in this media driver.
After this patch most supported formats work correctly. There are still
issues with the NV21 and NV61 formats, but that seems to be a separate
problem since NV12 and NV16 work and these formats use the same values.
So this can be fixed as a follow-up and shouldn't be a blocker for this
change that improves the driver's support.

The driver exposes 32-bit A/XRGB 8-8-8-8 as supported format but testing
shows that using this format produces frames with wrong colors. The test
was done with the following GStreamer pipeline:
$ gst-launch-1.0 videotestsrc num-buffers=20 ! video/x-raw,format=UYVY \
! v4l2video3convert ! video/x-raw,format=xRGB ! videoconvert ! kmssink
The manual seems to state that the Pixel Format are in Little Endianness
so instead use the 32-bit BGRA/X 8-8-8-8 pixel format. This format works
correctly when using the following pipeline:
$ gst-launch-1.0 videotestsrc num-buffers=20 ! video/x-raw,format=UYVY \
! v4l2video3convert ! video/x-raw,format=BGRx ! kmssink
This change is similar to commit 7f2816e51e ("[media] s5p-fimc: Changed
RGB32 to BGR32") that fixed the same issue on a different Samsung driver.

User-space applications can use the VIDIOC_REQBUFS ioctl to determine if a
memory mapped, user pointer or DMABUF based I/O is supported by a driver.
For example, GStreamer attempts to determine the I/O methods supported by
the driver by doing many VIDIOC_REQBUFS ioctl calls with different memory
types and count 0. And then the real VIDIOC_REQBUFS call with count == n
is be made to allocate the buffers. But for count 0, the driver not only
frees the buffers but also clears the format set before with VIDIOC_S_FMT.
This is a problem since STREAMON fails if a format isn't set but GStreamer
first sets a format and then tries to determine the supported I/O methods,
so the format will be cleared on REQBUFS(0), before the call to STREAMON.
To avoid this issue, only free the buffers on VIDIOC_REQBUFS(0) but don't
clear the format. Since is completely valid to set the format and then do
different calls to REQBUFS before a call to STREAMON.

For tiled format, we need to allocated a multiple of the row size. A
good example is for 1280x720, wich get adjusted to 1280x736. In tiles,
this mean Y plane is 20x23 and UV plane 20x12. Because of the rounding,
the previous code would only have enough space to fit half of the last

Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.

Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.
The patch was generated via the script below, and manually
adjusted if needed.

Instead of relying on the "simple-bus" compatible and the driver core
populating FIMC-IS child devices make the fimc-is driver populating
its child devices. This prevents issues related to accessing ISP_I2C
clock registers with corresponding power domain switched off, which
popped out after applying some pending IOMMU driver patches. Now the
I2C_ISP child devices will be instantiated only when required parent
device drivers are initialized and ready.

Since commit 04f59143b5
("i2c: let I2C masters ignore their children for PM")
the power.ignore_children flag is set when registering an I2C
adapter. Since I2C transfers are not managed by the fimc-isp-i2c
driver its clients use pm_runtime_* calls directly to communicate
required power state of the bus controller.
However, when the power.ignore_children flag is set that doesn't
work, so clear that flag back after registering the adapter.
While at it drop pm_runtime_enable() call on the i2c_adapter
as it is already done by the I2C subsystem when registering
I2C adapter.
This patch is meant as a minimal change to fix the regression,
eventually the I2C_ISPx clock handling will be moved to the
top level fimc-is driver and whole runtime PM code is going to
be dropped from the fimc-is-i2c module.

At probe time and when S_STD is called the driver will default to use
V4L2_FIELD_INTERLACED if the subdevice reports V4L2_FIELD_ALTERNATE. The
driver will only change the field type if the subdevice implements
G_STD, if not it will keep the default at V4L2_FIELD_ALTERNATE.
The user can always explicitly ask for V4L2_FIELD_ALTERNATE in S_FMT and

The media bus format reported by the adv7180 is wrong. Steve Longerbeam
posted a patch which changed the format to UYVY8_2X8 with the commit
message:
Change the media bus format from YUYV8_2X8 to UYVY8_2X8. Colors
now look correct when capturing with the i.mx6 backend. The other
option is to set the SWPC bit in register 0x27 to swap the Cr and Cb
output samples.
The rcar-vin driver was developed and tested with the adv7180 and
therefor suffers from the same issue, looking for the wrong media bus
format. The two errors corrected each other.
This patch takes Steve's patch and merge it with a fix for rcar-vin
driver. The rcar-vin driver is used used in together with the adv7180
och Koelsch and this ensures it will not break while fixing the adv7180
issue. I checked wit Steve and he was fine with me merging the patches.

The frame-end function releases and completes the buffers on the input
and output entities of the pipe before marking the pipe->state as
'STOPPED'. This introduces a race whereby with the pipe->state still
'RUNNING', a QBUF handler can commence processing a frame before the
frame_end function has completed.
In the event that this happens, a frame queued by QBUF hangs due to the
incorrect pipe->state setting which prevents vsp1_pipeline_run from
issuing a CMD_STRCMD.
By locking the entire function we prevent this from occurring, but we
also change the locking state of the buffer release code. This has been
analysed visually as acceptable, but it must be considered that this now
causes the video->irqlock to be taken under the pipe->irqlock context.

Since we really don't want to have to use any of the soc-camera code this patch
copies the relevant code and data structures from soc_mediabus and renames it to pxa_mbus_*.
The large table of formats has been culled a bit, removing formats that are not supported

Instead of the legacy behavior where it was required to wait for all
video buffers to be finished by the hardware, use a cancel like strategy
: as soon as the stop_streaming() call is done, abort all DMA transfers,
report the already buffers as failed and return.

This patch removes the soc_camera API dependency from pxa_camera.
In the current status :
- all previously captures are working the same on pxa270
- the s_crop() call was removed, judged not working
(see what happens soc_camera_s_crop() when get_crop() == NULL)
- if the pixel clock is provided by then sensor, ie. not MCLK, the dual
stage change is not handled yet.
=> there is no in-tree user of this, so I'll let it that way
- the MCLK is not yet finished, it's as in the legacy way,
ie. activated at video device opening and closed at video device
closing.
In a subsequence patch pxa_camera_mclk_ops should be used, and
platform data MCLK ignored. It will be the sensor's duty to request
the clock and enable it, which will end in pxa_camera_mclk_ops.

PM: Device fe948000.fdp1 failed to resume noirq: error 1
According to its documentation, rcar_fcp_enable() returns 0 on success
or a negative error code if an error occurs. Hence
fdp1_pm_runtime_resume() and vsp1_pm_runtime_resume() forward its return
value to their callers.
However, rcar_fcp_enable() forwards the return value of
pm_runtime_get_sync(), which can actually be 1 on success, leading to
the resume failure above.
To fix this, consider only negative values returned by
pm_runtime_get_sync() to be failures.

The driver's watchdog_workqueue has been replaced with system_wq since
it queues a single work item, &dev->watchdog_work, which calls for no
ordering requirement. The work item is involved in running the watchdog
timer and is not being used on a memory reclaim path.
Work item has been flushed in s5p_mfc_remove() to ensure
that there are no pending tasks while disconnecting the driver.

According to the V4L2 documentation the driver and card fields should be
used to identify the driver and the device but the gsc-m2m driver fills
those field using the platform device name, which in turn is the name of
the device DT node.
So not only the filled information isn't correct but also the same values
are used in the driver, card and bus_info fields.
Before this patch:
Driver Info (not using libv4l2):
Driver name : 13e00000.video-
Card type : 13e00000.video-scaler
Bus info : platform:13e00000.video-scaler
Driver version: 4.7.0

The driver fills in both the struct v4l2_capability driver and card fields
the same values, that is the driver's name plus the information if the dev
is a decoder or an encoder.
But the driver field has a fixed length of 16 bytes so the filled data is
truncated:
Driver Info (not using libv4l2):
Driver name : s5p-jpeg decode
Card type : s5p-jpeg decoder
Bus info : platform:11f50000.jpeg
Driver version: 4.7.0
Also, this field should only contain the driver's name so use just that.
The information if the device is a decoder or an encoder is in the card
type field anyways.

- removal of the media DocBook (since it's all in Sphinx now)
- videobuf2: Fix an allocation regression
- a few fixes related to the CEC drivers
* tag 'media/v4.8-5' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media:

doc-rst: Remove the media docbook
The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer. Thus the pointer can point to const data.
However the attributes do not have to be a bitfield. Instead unsigned
long will do fine:
1. This is just simpler. Both in terms of reading the code and setting
attributes. Instead of initializing local attributes on the stack
and passing pointer to it to dma_set_attr(), just set the bits.
2. It brings safeness and checking for const correctness because the
attributes are passed by value.

The newly added mtk-vcodec driver produces a number of warnings in an
ARM allmodconfig build, mainly since it assumes that dma_addr_t is
32-bit wide:
mtk-vcodec/venc/venc_vp8_if.c: In function 'vp8_enc_alloc_work_buf':
mtk-vcodec/venc/venc_vp8_if.c:212:191: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
mtk-vcodec/venc/venc_h264_if.c: In function 'h264_enc_alloc_work_buf':
mtk-vcodec/venc/venc_h264_if.c:297:190: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
This rearranges the format strings and type casts to what they should
have been in order to avoid the warnings. e0f80d8d62 ("[media]

were introduced at the same time, but missed two others.

The newly added FCP support in the vsp1 driver causes a link error
when CONFIG_RENESAS_FCP=m, since it's not reachable by built-in code:
drivers/media/built-in.o: In function `vsp1_remove':
:(.text+0xdeca0): undefined reference to `rcar_fcp_put'
drivers/media/built-in.o: In function `vsp1_probe':
:(.text+0xdef44): undefined reference to `rcar_fcp_get'
We already have a conditional dependency on FCP that requires
it for ARM64, so for all others we just have to prevent setting
RENESAS_VSP1=y when RENESAS_FCP=m by extending the FCP dependency.
